If you don't want to spend several dollars on a tiny bottle of salt substitute from the grocery store, try making your own!  Here's what you should do:

Harvest your herbs.  Use basil, Asian basil, oregano, oriental oregano, and rosemary. Dry slowly in oven.  Crush using a mortar and pestle or another method of your choice.  Add Kentucky steak seasoning, pepper medley, and a little cumin and paprika. This is terrific as a salt substitue and only requires a quick crush.
